Lucas distributor type for model 100 - 1960

[ThomasMoRo]

Does anyone have a spare parts catalog that also includes the 1960 Type 100?

I'm looking for the number of the matching Lucas distributor!

My data only goes up to 1959 and doesn't include the Model 100.

PS: My plan is to use an electronic distributor from 123Ignition, and I need some data for that.

Dear Thomas,
Regarding 123 distributors. This is just a suggestion. I have only had one 123 distributor and strangely enough, I bought it for a Volvo 123GT. The car seemed a bit lethargic to me coming from Triumphs and Rovers and I suspected an ignition fault that was eluding me. However, I can truthfully say that despite the eye watering amount of money the distributor cost, it made not a bit of difference.

Over the years, that and other experiences have lead me to look carefully at ignition components. If we know that a car with mechanical components and simple electrics worked reliably in the past, there is no reason why it should not do so today. Without wanting to write too much, I have found that cracked or broken plastic insulating components are a common source of problems, as are ill fitting or poorly aligned contact points, poor HT leads (broken wires just inside the insulation where they bend - modern copper does not bend much before it breaks), poor LT connections, distributor arms with rivets, cheap condensers. Finally, I have been testing coils and find considerable differences in the spark potential across various models. These can be tested with one of these :

Spark plugs can also be simply tested and compared with one of these:

I've also found that it isn't that one product doesn't work but, when tested, it doesn't work as well as another. I appreciate you may have been down this route already so do excuse the suggestion if you have exhausted all other avenues.

I am not saying that electronic ignition isn't worth it. I would question, though, whether a very similar result cannot be obtained through close examination of the relatively few simple components that make up electro mechanical ignition. I have a friend who used to have an Austin Twenty which is documented as having covered around 750,000 miles on a magneto and it's still on the go !
